SAN FRANCISCO — A comprehensive survey of the University of California system has found nearly one-quarter of students, staff and faculty members say they have felt intimidated or on the receiving end of hostile behavior while at the system’s 10 campuses and major off-campus offices.

UC officials said Wednesday that the 93-question survey was part of an effort to promote respect and diversity following a series of charged incidents that included a noose and KKK hood being found at UC San Diego, complaints about bias from UCLA staff and ongoing tensions between Palestinian supporters and Jewish students at several schools.

Provost Aimee Dorr says that while 79 percent of the 104,208 respondents said they were comfortable at UC, administrators will analyze the data to look for areas in which to improve.
